Abstract

The formation of multiple transmission peaks with flat-top shapes in photonic crystals with a super-lattice structure is presented. By reducing the confinement strength from the barriers, the photon quantized states within each mini-bands of super-lattice structures can be coupled to each other, and multiple transmission peaks with flat-top shapes are formed. The performance of these flat-top transmission peaks is investigated in detail, and the formula to determine the frequency locations of these peaks is presented. These results may facilitate the potential applications of multiple channeled filtering based on photonic hetero-structures.
